AIR HEATER.

Application filed July 7, 1924, Serial No. 724,642. Renewed November 7, 1925.

To all whom it may concern:

Be it known that I, THOMAS Jnrrnnson PEACE, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in an Air Heater, of which the following is a specification.

This invention relates to an improved heating apparatus which may be, more specifically referredto as an air heater, the same being'adapted for general house and hotel use. 7

It is my object to provide a heater of this class wherein the air is circulated through heated drums underthe action ofa fan so as to insure a constant flow of air from the source to the point of discharge in the room.

It is a feature of the invention to provide a plurality of superposed. air heating drums with burners in association therewith, the flames from the burners impinging upon the drums to heat the latter to a high degree so that the air passingtherethrough will in turn be intensely heated, these drums and burners being housed within a jacket or casing to obtain the full benefit of the heat from the burners.

Other features and advantages of the invention will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:

Figure 1 represents a central vertical section, with parts in elevation, of a heating apparatus constructed in accordance with the present invention.

Figure 2 represents an enlarged detail section through two of the air drums.

Figure 3 is a horizontal section taken approximately on the plane of the line 33 of Figure 1.

Referring now to the drawing in detail, the numeral 1 designates a vertically elongated outer casing or jacket which may be made up of two plies of sheet metal of any desirable quality. Although I have not shown this, I propose to interpose asbestos between the plies and metal to render the casing heat-proof. The inner sheet of material is formed at its top to provide an apertured hot air escape dome 2, while the corresponding portion of the outer sheet is formulated in any manner to provide a suit able hotair dlscharge 3. Furthermore, if desired, the acket may be prov ded at vertically spaced points on one side with trans parent windows or doors 4: which maybe 'mounted in any appropriate manner either to permit them to be swung open, slid open, or removed. i

. As before intimated, the jacket just described houses an air conduit which in the present instance is composed of. a plurality of superposed drums 5 and 6. While these drums couldbe of any suitable configuration other than that shown, they are preferably of. the shape shown and are separateand connected together through the medium of a constricted'neck, this neck being joined to the body portions through the medium of conical flame spreading surfaces 7. The upper drum is substantially ovate in cross section to provide clearance space between its opposedflfiattened sides and the adjacent portions of the walls of the casing. The lower drum 5 is supported upon the neck of a hollow base 8 and this base is provided on one side with an air intake 9 in which an electric air circulating fan 10 is located. Although I have not shown it, I propose to attach a cold air conveying pipe to the intake 9, the conveying pipe coming from any suitable source, such as from a register in the floor of the building above. Positioned in the casing between the air drums 5 and 6 is a horizontal partition 11. It will be observed that this partition 11 is provided with apertures to permit passage of efiluent particles of combustion therein and downward air currents therethrough. Also, disposed above the upper drum is a rotary damper 12.

Surrounding the joining necks between the drums and the lower drum base are superposed ring-like burners 13. By preference, these will be gas burners and will. be provided with a plurality of apertures for caus- .ing a circular flame to impinge upon each air drum. The burners are connected together by a pipe 14 and each burner is provided with a control valve 15. The gas supply pipe is indicated by the reference character 16.

' Although it is not essential, I propose to utilize the heating drums for the purpose of heating water and in carrying out this end I simply provide a coil 17 for surrounding one or more of the air drums as shown, this coil being in communication with a wa ter reservoir or tank 18 and the discharge end 19 thereof leading to any suitable point e i discharge.

From the foregoing it is obvious thatthe cold air enters the base 8 through the intake 51 and travels upwardly in the direction of the arrows, a forced circulation being produced by the aid of the fan 10. The flame from the burners 13 impinges upon the lower inclined surfaces of the drums 5 and (i and scr cs to heat these to a high degree. Consequently, the air passing through these drums will come in contact with the heated Walls and will in turn become heated to a high degree before passing out through the discharge passage 3. As before stated, the discharge passage may communicate with one or more radiators in the room or building to be heated. The discharge of the heated air may be controlled more or less by the regulating damper 12. lVhile the drums are serving to heat the air passing therethrough, they also serve to heat the water passing from the tank 18 through the coil 17 and pipe 19. In practice, this coil may be of any size or may be applied to both of the drums.

Although I have shown and described the specific embodiment of the invention, I Wish it to be understood that minor changes coming within the scope of the adjoined claims may be resorted to if desired. For instance, while I have shown but a pair of superposed burners, I Wish it to be understood that more than two burners may be used if necessary.

Having thus described the invention, what I claim is:

1. A heating apparatus comprising a pluralit-y of superposed hollow ail heating drums connected together through the medium of necks. a hollow base upon which said drums are mounted, said base being provided with an air intake, superposed ringlihc apertured burners surrounding the neck between the drums and the lower drum and said base, a valved fluid supply pipe connecting sait burners together. a casing tor said drums, said casing being provided with a discharge for the heated air, and a. damper mounted in said casing and cooperating' with said discharge.

2. A heating apparatus of the class dcscribed comprising, a plurality of superposcd holler air heating drums, each drum being provided with conical flame spreading surfaces and with a constricted neck connccted to the corresponding part of the adjacent drum, annular apertured burners surrounding said neck, a valved fuel supply pipe connecting said burners together, a hollow base upon which said drums are supported, said base being provided with a restricted cold air intalie, a circulating fan for the air disposed in said intake, a casing tor the drums and lnu'ners supported from said base, a hot air discharge controi 'g damper arranged in said casin and a h zontal partition disposed in the casing Lctween the upper and lower dru:

in testimony whereof I aiii my signature.
